Mazda Bongo Oil Filters (Possible alternatives)

 

Dropping this information here as a future reminder to myself, in the event that I buy an old Bongo.

• Diesel full-flow (common on RF-family diesels)
• Mazda OE:
• RFY6-14-302 (also shown as RFY2-14-302 / RFY2-14-302; older numbers may supersede to this)
• Possible aftermarket equivalents (double-check before use):
• MANN: W 811/80
• MAHLE/Knecht: OC 205
• BOSCH: 0 451 103 316
• WIX: WL7171
• FRAM: PH5317
• 2.5L WL diesel (often Bongo Friendee / late-era imports)
• Mazda OE:
• WLY0-14-302
• Possible aftermarket equivalents (double-check before use):
• MANN: WP 928/80
• MAHLE/Knecht: OC 275
• BOSCH: 0 986 452 062
• WIX: WL7175
• Petrol engines (Mazda “M20x1.5” style spin-on used across many models)
• Mazda OE:
• FEY0-14-302 (Mazda shows this with alternates like B6Y2-14-302-P1)
• Possible aftermarket equivalents (double-check before use):
• FRAM: PH3593A
• Purolator: L14460 / L14620
• WIX: 51064

• IMPORTANT NOTES
• Diesel Secondary Filter: If there is a second “bypass / side-stream” oil filter
• Some setups list a separate bypass filter that’s used in addition to the main full-flow filter.
• Mazda OE:
• 8259-23-802
• K710-23-802
• R21423802
• Possible aftermarket equivalents (double-check before use):
• Blue Print: ADM52104
• Nipparts: J1313006
• Quick “don’t-get-burned” checks
• Confirm the thread, gasket diameter, and height match.
• Especially true for WL and RF filters.
• If you see a reference to “bypass/side-stream,” assume it’s a second filter, not a substitute for the main one.
